Which muscle group is contraindicated for IM injections in children?

The dorsogluteal muscle group is contraindicated for intramuscular (IM) injections in children primarily due to safety concerns. This site is located in close proximity to the sciatic nerve and major blood vessels, which increases the risk of nerve injury and bleeding when administering an injection. In young children, the muscle mass in the dorsogluteal area is often insufficient, and improper technique can lead to complications.

In contrast, the vastus lateralis muscle is preferred for IM injections in children because it is a large muscle located away from major nerves and blood vessels. The ventrogluteal muscle is also an appropriate site for IM injections as it provides a safe option with minimal risk of injury. The deltoid muscle can be used in older children and adolescents, but it is less commonly used for infants and young children due to its smaller size and limited volume capacity. Thus, avoiding the dorsogluteal site in pediatric patients ensures a safer injection practice.
